It is 2, because you make the mixed number into an improper fraction 7/2 times 4/7, and then you cross simplify and you get 1/1 times 2/1 which is 2

one taco supreme and two pan pizzas provide 3850 calories. Two taco supremes and one pan pizza provide 3770 calories . Find the

Sedaia [141]

Answer:

Taco supreme is 1230 calories

Pan pizza is 1310 calories

Step-by-step explanation:

Let's denote taco supreme as T and pan pizza az P. We have:

T+2*P = 3850 and 2*T + P = 3770

If we add the equations we get 3*T+3*P = 7620

3*(T+P) = 7620

T+P = 2540 => we can use T=2540-P

Back to one of the first equations we get 2540-P+2*P=3850

P=3850-2540= 1310

=>T= 2540-1310= 1230

What is the zero in the quadratic function f(x)= 9x^2-54x-19?

Alex17521 [72]

Answer:

6.33... and 0.333...

Step-by-step explanation:

The quadratic formula is

$x=\frac{-b+\sqrt{b^2-4ac} }{2a}$ .

It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. Using the formula will require less work than finding the factors if factorable. We will substitute a=9, b=-54 and c=-19.

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-54)+/-\sqrt{(-54)^2-4(9)(-19)} }{2(9)}\\x=\frac{54+/-\sqrt{2916+684} }{18}$

We will now solve for the plus and the minus.

The plus,,,

$x=\frac{54+\sqrt{3600}}{18}\\x=\frac{54+60}{18}\\x=\frac{114}{18}\\x=6.3$

and the minus...

$x=\frac{54-\sqrt{3600}}{18}\\x=\frac{54-60}{18}\\x=\frac{-6}{18}\\x=-0.333...$
